自己写的比较简陋的自动增删input

var context = $("#form_40213454w534532432dgtdtreteb34542");

var html = "<tr height='30'>";

html += "<td class='tdCenter' name='sequence' width='50'></td>";

html += "<td class='tdleft' width=''>";

html += "<input name='require' style='width:100%;height:30px;border:none;' onchange='dm.lsproductiondispatchplan.onChangeRequire()'/>";

html += "</td></tr>";

$('#require', context).append(html);

var input_number = $("[name=require]", context);

var len = input_number.length;

$("[name=require]", context).each(function(i) {

var val = $(this).val();

if (val == "" && i != (len - 1)) {

$(this).parent().parent().remove();

}

;

});

// 添加序列号,每回都是重新赋值

var index1 = 0;

$("[name=sequence]", context).each(function() {

index1++;

$(this).text(index1);

});
